Troubleshooting Guide

4.2

1. The Foremost Inspecting Items

⑴The input voltage must be within +10% tolerance of the rated Voltage. If it

is not the case, the air-conditioner will probably not work normally.

⑵Check the connecting cord between indoor unit and outdoor unit to see if

it is properly connected. The connecting must be done according to the

wiring diagram, please also notice that even different models may have the

connecting cord of the same specification.

Please check if the marks at the connecting terminal and the marks on the

cord can match, otherwise, the air-conditioner will not work normally.

⑶If the following phenomena are found, the problem is not from the

air-conditioner itself.

11

5

The compressor works

discontinuously at cooling and

dehumidifying mode, and the indoor

fan motor slows down.

The compressor stops internally or the fan

motor slows down to prevent the indoor heat

exchanger from being frozen.

NO. Problems Causes

1

The motor is heard operating but the

air-conditioner dose not work when

the indoor unit is powered on

Since the air-conditioner is powered on, it

will come to working condition as long as you

press the ON/OFF button of the remote

control and the Signal is well received.

2

The compressor stops running but

the indoor fan motor keeps working

when it is at cooling mode with the

indoor temperature higher than set

temperature.

If you turn off the air-conditioner and restart it

immediately, it will return to normal in 3

minutes, after that, the air-conditioner will

automatically adjust the indoor fan speed to

what you set.

3

The compressor works

discontinuously at dehumidifying

mode.

The air-conditioner will automatically control

the working of the compressor according to

the inside temperature

4

The air-conditioner does not work

while the LED display is on.

The TIMER is set with the air-conditioner; it

will be in hold on condition. If the TIMER

setting is cancelled, the air-conditioner will

return to normal working condition
